Filed: 1981-02-23
Abstract: PURPOSE:To reduce a temperature variation against a set temperature, by providing an AC power source, a heater and a phase controlling circuit for controlling a temperature of the heater by phase control of the electric power source. CONSTITUTION:A temperature is controlled by varying from the outside the phase of an ignition pulse of an ignition pulse generating circuit P for igniting thyristors SCR1, SCR2 by optional phase, and varying the electric power to be supplied to a heater 5. That is to say, a current controlled by a phase controlling circuit 2, rectified and smoothed flows to the heater 5, therefore, a temperature variation against a set temperature can be reduced.

Title: Ground fault detector
Inventor: HATAKEYAMA YOSHIHIRO
IPC: H02H3/347
Filed: 1990-02-06
Abstract: PURPOSE:To avoid an unnecessary operation caused by a rush current by a method wherein a ground fault component is subjected to full-wave conversion and outputted to a level discriminator and, if the output signal continues a predetermined period, a switching device is operated. CONSTITUTION:The first monostable multivibrator 21-1 of a continuous signal discriminator 21 outputs a first pulse (f) having a predetermined time width at every time when an output signal (d) from a level discriminator 10 is received. If the output waveform exceeds a discrimination level continuously, the time width of the pulse becomes seemingly long. On the other hand, the second monostable multivibrator 21-2 of the continuous signal discriminator 21 outputs a second pulse (g) having a predetermined time width and, after this pulse is outputted and while this pulse lasts, the output signal (d) from the level discriminator 10 is neglected. When the logical product of the two pulses (f) and (g) is obtained, the AND circuit 21-3 of the continuous signal discriminator 21 outputs an operation signal (h) for a switching device 8 to perform ground fault detection and cut-off.

Abstract: PURPOSE:To detect a signal with high S/N by providing an optical path traveling direction change means in an optical path, the polarizing reflected light from a first sensor and/or a second sensor outside the optical path to a non- polarizing beam splitter. CONSTITUTION:A beam of light advancing from the non-polarizing beam splitter 11 to a sensor 15 is bent via the optical path traveling direction change means (prisms 11a and 11b). At the prism 11a, part of parallel beams of light passing a collimator lens 109 is reflected on the plane of the non-polarizing beam split ter, and advances to the outgoing plane of the prism 11a, however, it is not radiated perpendicularly from the outgoing plane, therefore, it is made incident on the light receiving part of the sensor 15 obliquely, and reflected light from a cover plate advances in a direction shown in dotted line, and is separated from the optical path to the non-polarizing beam splitter 11. Thereby, no reflected light is made incident on the second sensor 14, which prevents the signal for reproduction from being disturbed. In such a way, it is possible to stably perform the recording and reproduction of information by detecting the signal with high S/N.
